Description

Technical Field

[0001] The invention relates to the technical field of dental medical instruments, in particular to a wire-drawing type interdental wedge. Background Art

[0002] Nowadays, dental methods and equipment are developing day by day, and the demand for tooth filling treatment is also increasing. Currently, in the clinical practice of dental treatment, doctors use a tool called a tooth gap wedge to insert it into the tooth gap for fixed support to implement tooth filling.

[0003] The size and shape of the interdental space (i.e., the gingival extension space) vary greatly between different affected teeth and different tooth positions, so interdental wedges of various sizes and shapes are designed. Existing interdental wedges are mostly wedge-shaped, with one end large and the other end pointed, which can be easily inserted into the interdental space. However, existing interdental wedges can only ensure close contact between the cheek and tongue, and a gap will appear on the other side of the cheek and tongue. They cannot fill the entire interdental space tightly, causing an overhang in the interdental space or sequelae in the later stage of filling. Moreover, interdental wedges used clinically are mostly made of wood and hard plastic. Even if a variety of sizes and shapes are designed, the degree of compliance is still relatively low compared with the interdental spaces of various sizes in clinical practice. Dentists need to conduct repeated tests or trim the interdental wedges to fit the interdental space, which is time-consuming and labor-intensive. Summary of the invention

[0004] The purpose of the present invention is to provide a pull-wire type interdental wedge, which can be placed in the interdental space more conveniently, and after being pulled, the entire interdental space can be tightly plugged, so that the forming piece can be closely contacted with the hole-shaped gingival wall, and can adapt to the space of different interdental spaces, and the gingival walls on both sides of the buccal and lingual sides can be tightly plugged to avoid overhangs, without the need to design multiple sizes, and has a wider range of adaptability.

[0005] To achieve the above object, the present invention provides the following solutions:

[0006] The present invention provides a pull-wire type tooth gap wedge, comprising a gap wedge body and a pull wire, wherein the gap wedge body is an elastic body, and a through hole is arranged through the center of the gap wedge body along the length direction, and the pull wire is fixed in the through hole and protrudes from the two ends of the gap wedge body, and the gap wedge body comprises a small end and a large end, and the size gradually increases from the small end to the large end so that the gap wedge body is wedge-shaped, and at least one recessed area is circumferentially arranged on the outer wall of the gap wedge body.

[0007] Preferably, the longitudinal cross-section of the gap wedge body is an isosceles triangle.

[0008] Preferably, the longitudinal cross-section of the gap wedge body is an equilateral triangle.

[0009] Preferably, each corner of the equilateral triangle is in an arc shape.

[0010] Preferably, there are two recessed areas, and the connection between each recessed area and the outer wall surface of the gap wedge body is arc-shaped.

[0011] Preferably, the outer wall edge of the gap wedge body is gently wavy from the small end to the large end.

[0012] Preferably, the tip of the small end includes a tapered portion.

[0013] Preferably, the tip of the tapered portion is rounded, and the connection between the tapered portion and the small end is rounded.

[0014] Compared with the prior art, the present invention has achieved the following beneficial technical effects:

[0015] The wire-type interdental wedge provided by the present invention has an elastic body, which can be squeezed and deformed when subjected to external force, and can adapt to interdental spaces of various sizes, and can also protect the gums from damage. The wire is bonded and connected in the through hole, and protrudes from the two ends of the wedge body, so that the wedge body is tightly adhered around the wire. When the wire is pulled, the wedge body moves with the wire, which is more convenient to use. The wedge body is wedge-shaped, so that the interdental wedge can enter the interdental space more conveniently. By setting two recessed areas, the outer wall edge of the wedge body is gently wavy from the small end to the large end, which can meet the needs of interdental spaces of various sizes and adapt to a wider range, and ensure that the wedge is not too long to affect the use. In addition, the recessed area can make the gingival walls on both sides of the buccal and tongue tight, and play a supporting and fixing role on the gingival walls on both sides, avoiding overhangs and avoiding sequelae in the later stage of filling. When the wedge body is pulled, it will gradually enter the tooth gap from the small end. The wedge body entering the tooth gap will be squeezed and deformed and shrink. After passing through the minimum gap area, it will recover and expand. The recessed area can make the gingival walls on both sides of the buccal and lingual sides of the hole be tightly plugged, so that the forming piece fits closely to the entire gingival wall, so that no overhang will be produced after filling, avoiding the sequelae of filling in the later stage.

[0021] The present invention provides a wire-type interdental wedge, such as Figure 1-Figure 4 As shown, the gap wedge body 1 and the pull wire 2 are included. The gap wedge body 1 is an elastic body. The gap wedge body 1 made of the elastic body will be squeezed and deformed when subjected to external force, so that it can adapt to the interdental spaces of various sizes and protect the gums from damage. The gap wedge body 1 is provided with a through hole 3 running through the center along the length direction. The pull wire 2 is fixed in the through hole 3 and protrudes from the two ends of the gap wedge body 1. The fixing method is preferably an adhesive connection, so that the gap wedge body 1 is tightly adhered around the pull wire 2. When the pull wire 2 is pulled, the gap wedge body 1 will move with the pull wire 2, which is more convenient to use. The gap wedge body 1 includes a small end 4 and a large end 5, and the size gradually increases from the small end 4 to the large end 5 so that the gap wedge body 1 is wedge-shaped, so that the interdental wedge can enter the interdental space more conveniently. The outer wall of the gap wedge body 1 is provided with at least one recessed area 6 circumferentially. In a preferred embodiment, there are two recessed areas 6. By setting two recessed areas 6, the outer wall edge of the gap wedge body 1 is gently wavy from the small end 4 to the large end 5, which not only meets the use of various sizes of tooth gaps and has a wider range of applications, but also ensures that the tooth gap wedge will not be too long to affect the use. In addition, the recessed area 6 can make the gingival walls on both sides of the cheek and tongue plugged tightly, and play a supporting and fixing role on the gingival walls on both sides, avoiding overhangs and avoiding sequelae in the later stage of filling. When the pull wire 2 is pulled, the gap wedge body 1 will gradually enter the tooth gap from the small end 4. The gap wedge body 1 entering the tooth gap will be squeezed and deformed and shrunk. After passing through the minimum gap area, it will recover and become larger. The recessed area 6 will make the gingival walls on both sides of the hole-shaped cheek and tongue plugged tightly, so that the forming sheet fits the entire gingival wall tightly, so that no overhangs will be produced after filling, and sequelae in the later stage of filling will be avoided.

[0022] In this embodiment, the longitudinal section of the gap wedge body 1 is an isosceles triangle. In a preferred embodiment, the longitudinal section of the gap wedge body 1 is an equilateral triangle, so that the gap wedge body 1 is more consistent with the spatial form of the tooth gap, and the tooth gap wedge can be more conveniently plugged into the tooth gap. In addition, each corner of the equilateral triangle is an arc shape, and the connection between each recessed area 6 and the outer wall surface of the gap wedge body 1 is arc-shaped, which further protects the gums from damage, and the gap wedge body 1 is more convenient to enter the tooth gap.

[0023] The tip of the small end 4 of the gap wedge body 1 includes a tapered portion 7, the tip of the tapered portion 7 is rounded, and the connection between the tapered portion 7 and the small end 4 is rounded. By providing the tapered portion 7, the front end of the interdental gap wedge can more conveniently enter the interdental gap, and the tapered portion 7 and its connection are rounded, which further ensures that the gums are not damaged.

[0024] The wire-type interdental wedge provided by the present invention can be used in a specific application process. When a tooth cavity is repaired clinically, after the cavity is prepared and the forming sheet is placed, the wire 2 at the small end 4 of the wire-type interdental wedge can be easily and conveniently placed into the interdental cavity. Then, the wire 2 is clamped with a tool such as tweezers, and the wire 2 is pulled toward the buccal and lingual side so that the tapered portion 7 and the small end 4 of the interdental wedge body 1 enter the interdental cavity in sequence. Then, the wire is gradually tightened with force until the forming sheet is close to the gingival wall, so that a recessed area 6 on the interdental wedge body 1 is located exactly in the middle of the bottom of the cavity. The gingival walls on both sides of the cavity's buccal and lingual sides can be plugged tightly, and the forming sheet can be tightly fitted to the entire gingival wall. The wire-type interdental wedge can more conveniently place the interdental wedge into the interdental cavity, and after pulling, the interdental wedge body 1 can plug the entire cavity, so that the forming sheet is in close contact with the cavity's gingival wall. It can adapt to spaces with various differences in interdental cavity, and can plug the gingival walls on both sides of the buccal and lingual sides to avoid overhangs. There is no need to design multiple sizes, and the adaptability is wider.

[0025] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
